Isn't this Professor Mochizuki? Fortunately. ”

Although he still had a smile on his face, as soon as Schultz opened his mouth, Lu Zhou smelled gunpowder.

Apparently hearing this, Professor Mochizuki raised his chin slightly, as if to express his disdain with his nostrils, and replied formulaically.

"Hello, Professor Schultz, long time no see."

"Yes, it's been a long time, after all, it's not easy to see you, so I can't trouble Mr. Mori Shigefumi to 'introduce' every time."

"Hehehehe."

Looking at the sparks of electricity rushing between the two, Lu Zhou, who was standing in the middle, felt a big head.

Some time ago, Mochizuki Shinichi didn't reply to his email, and he thought that he was "blocked" by him because he didn't speak well, but he didn't expect this guy to come over in person.

He didn't expect it to be such a coincidence, which happened to make this guy and Schultz collide.

Frowning slightly, even Perelman could see the mismatch between the two, so he coughed lightly and said.

"If you have something to do, why don't you settle it privately first, and then we'll move on."

"No," Schultz said with a sunny smile on his face, "I don't have any contradiction with Professor Mochizuki. And you came just in time to be discussing those five hundred pages of scrap paper — oh no, the paper. ”

Squinting at him for a while, Shinichi Mochizuki didn't speak, just looked at Lu Zhou.

"I don't have much to say to him, I'm here for you."

Lu Zhou sighed and said.

"It's a coincidence."

"It's all here, so let's continue."

As he spoke, he turned to face the whiteboard, and no longer bothered about the contradictions between the two behind him, and began his own board book.

When the first line was written, the two people, who were still looking at each other, finally restrained their overflowing emotions and gradually returned their attention to academic issues.

Especially when Lu Zhou wrote the fifth line of the equation, Shinichi Mochizuki's eyes couldn't help but narrow slightly.

Far Abelian Geometric Method!

As the pioneer of this mathematical language, he did not feel too surprised by the mathematical language itself that he invented.

And what really made him feel incredible was that someone could use it so skillfully, even to the point that he couldn't help but applaud.

It was probably the first time he had seen something so surprising outside of Kyoto University.

For the vast majority of people, the strange mathematical symbols he created alone are enough to make the scalp tingle. Not to mention the use of those mathematical symbols to pile up a complete argumentation process.

Ten minutes.

Twenty minutes.

Finally, half an hour passed, and the five whiteboards were almost filled with dense formulas.

Just when the three people standing in front of the whiteboard and watching had already begun to feel some soreness in their necks, Lu Zhou finally withdrew the marker pen printed on the whiteboard, moved his arm and took half a step back.

Finally seeing the last of the equations on the whiteboard, the surprised expression on Shinichi Mochizuki's face gradually turned solemn, and then changed back to that incredible appearance.

At about the same time, after reading the equation on the whiteboard, a smile gradually appeared on Schultz's face, and it was obvious that Lu Zhou had come up with a similar result to him.

As for Professor Perelman, the expression on his face still did not change, but there was a hint of thoughtfulness in his eyes.

“…… The incompatibility of spatial measures means that the final inequality does not compare two quantities that should really be compared......"

Looking at Shinichi Mochizuki, who was already completely lost in thought, Lu Zhou continued softly, "But if you change the proof, as I wrote in Eq. 2.1, make the spatial measures compatible with each other. ”

Schultz laughed and said, "Then this inequality will lose its meaning again." ”

Lu Zhou nodded: "Yes, but I suggest that you don't interject." ”

Shrugging his shoulders, Schultz closed his mouth a little boredly, glanced at Shinichi Mochizuki who was silent next to him, and walked over to make himself a cup of coffee.

The deduction has been carried out here, and there is no suspense.

He admits that Lu Zhou's way of analyzing problems is closer to the essence than himself.

Even when he falsified the 3.12 inference, his argument was infinitely close to proving the inference and deducing the final result of the ABC conjecture.

However, in the end, it was still a little bit worse.

It is precisely that point that forces all the fault tolerance to a corner that cannot be tolerated, and at the same time makes the more than 500 pages of essays on culture come to naught.

Looking intently at the equation on the whiteboard, Shinichi Mochizuki didn't speak for a long time.

Looking at Professor Mochizuki, who was silent, Lu Zhou thought for a while and said thoughtfully.

"There is something unique about the formulation of Far Abelian geometry...... It took me a lot of time just to figure out what the symbols meant. If there is no misunderstanding of expression, this is probably the process of argumentation in which you replace 'provable' or 'obvious' in your paper. ”

Mochizuki nodded a little.

"Yes."

Lu Zhou: "Then do you have any questions?" ”

Mochizuki shook his head.

"Nope."

Without a doubt, it was the most perfect derivation he could think of, even more perfect than he expected.

That's why ......

He couldn't think of any way to refute it.

Looking at Shinichi Mochizuki, who fell silent, Lu Zhou thought for a moment, and then suddenly spoke: "In fact, Far Abelian Geometry has many remarkable points when solving abstract mathematical problems, but the price it takes to master this tool is really high. I think that if a knowledge wants to be passed on, it is the premise of everything to be understood. ”

Staring at the equation on the whiteboard with a frown, Shinichi Mochizuki said in an indifferent tone.

"I don't care."

"And what's the point of your work?"

"Meaning?"

"That's right," Lu Zhou nodded, "Most scholars are confused about your work, and there are very few scholars in the mathematical community who know far from Abelian geometry, and the only people who understand your work are mostly your students or colleagues." Maybe you can still work in mathematics for 10 or 20 years, but what about 30 or even 50 years from now? ”

"Maybe your theory is lucky enough that your students do the work you didn't do for you, combing through the obscure things into mathematical principles that can be understood and accepted by the vast majority of people. A hundred years later, there is a 1 in 10,000 chance that this knowledge will sprout new branches in unfamiliar soil. ”

"However, if it's not as lucky as we think, your students aren't outdoing you in this area. For fifty years at most, everything you have done in this field will no longer be remembered and forgotten as if it had never been in this world. ”

"Of course you don't care," shrugging his shoulders and looking at Shinichi Mochizuki, who had fallen silent, Lu Zhou said in an indifferent tone, "I just feel a little sorry for you." ”

After being silent for a long time, Professor Mochizuki, who looked at the lines of calculations on the whiteboard, suddenly spoke.

"May I ask a question?"

Lu Zhou: "Of course. ”

Shinichi Mochizuki: "You really, it only took two days?" ”

Lu Zhou smiled embarrassedly and said, "Sort of, although I basically didn't have much rest in those two days." ”

Shinichi Mochizuki, who had a complicated expression written on his face and didn't know what he was thinking, nodded silently.

This time he didn't say anything, but just turned around and walked away.

……

The seminar continues.

After listening to Lu Zhou's explanation, both Perelman and Professor Schultz agreed that the only way to solve this counterintuitive mathematical problem is through counterintuitive mathematical tools.

It is best to be a language that is independent of existing mathematical methods and is specifically used to describe this particular kind of Diophantine equation problem.

As for the problem breakthrough.

In Lu Zhou's view, it can be considered to start with the refinement of Baker's theorem and gradually move towards the results of the ABC conjecture.

Having an unexpected interest in the subject, Schultz temporarily took up residence in the faculty dormitory of Jinling University.

Although Lu Zhou said that he could arrange a hotel with better conditions for him, he refused on the grounds that the distance was too far and inconvenient.

As for Shinichi Mochizuki, he has disappeared since that day, and no one can be contacted, and there is no intention of replying to the email.

Lu Zhou, who thought that he had returned to China, didn't pay attention to him, but what he didn't expect was that on the morning of the third day, when the new day of the seminar was about to start, he appeared again.

"You're right, I thought about it for a long time after I got back to the hotel."

“…… Whether it's the proof that refutes me, or the suggestion about far-abelian geometry. ”

"If at the end of the day no one remembers that I did these jobs, then all the efforts I put into this field could be meaningless waste paper when I retire. It would have been fine if I had been dead by then, but if I had been alive, it would have become an ordeal. ”

As he spoke, Professor Mochizuki pointed his nostrils to the side with some embarrassment, coughed lightly and continued.

“…… When I return to Kyoto this time, I will take a little time to try something that I have not done before. ”

"And before that, I want to stay here for a while."

"What was left unfinished more than a decade ago, I want to put an end to it."

Looking at Shinichi Mochizuki in surprise, Lu Zhou didn't expect that he would admit his mistake so frankly, let alone that he would propose to stay on Kim Dae's side for a while.

This is the same as the rumors in the mathematical community......

It's a little different.

Lu Zhou, who was slightly stunned and came back to his senses, immediately smiled and stretched out his right hand.

"I'm glad you were able to think so...... Also, you are welcome to join us. ”

After shaking hands, Shinichi Mochizuki let go of Lu Zhou's right hand and continued to look at Schultz, who was standing aside.

"I think we have a very serious misunderstanding of each other...... But don't expect me to apologize to you, it's not me alone. ”

Smiling and holding his arms, Schultz said teasingly.

"It's okay, I didn't expect it. Also, while there are obvious problems with your proof process, we all agree that your idea is still feasible and that we need to create a new mathematical language to describe the problem...... Welcome to our group, it seems that L· S· P has to be changed to L· S· P· M too. ”

As he spoke, he smiled and held out his right hand.

Looking at the outstretched right hand, Shinichi Mochizuki frowned, hesitated for a moment, and finally shook it.

"Cooperation...... Pleasant. ”

"This is definitely the most luxurious lineup in the history of mathematics," looking at the two shaking hands, Lu Zhou said jokingly, "I bet, at least one of them." ”

"I think we can remove the prefix 'one,'" Schultz said jokingly, looking at Lu Zhou, "After all, we have Professor Lu." ”
